Rodinia

Rodinia is the sixth continent to form on earth. Rodinia was mostly present for the Mesoproterozoic and Neoproterozoic Eras. Rodinia formed 1-1.1 billion years ago in the Stenian Period, and broke up 740-750 million years ago, in the late Tonian. Rodinia may have broken up due to glaciation in the Cryogenian, which froze all the land and sea for a few million years.
